Hi Pete,
Thank you so much for your patiently responding my questions. In fact, I have
an idea to use conversation browse bean. User can browsing the search results,
then he/she can either create a new instance or edit an existing instance
through another conversation bean from the browsing page. After he/she
finishes, the user can go back the previous conversation browse bean. However,
I couldn't get it work. The codes are as following. Thank you very much in
advance.
